Answer: aspartame has more
Explanation: Aspartame contains 4 calories per gram (g), similar to sugar. It is, however, around 200 times sweeter than sugar. This means that only a tiny amount of aspartame is necessary to sweeten foods and drinks. so answer is aspartame
Aspartame has more calories. Why? Because aspartame manufactures four calorie kilograms of energy per gram when it's transfigured. Why is table sugar not the answer? Because table sugar manufactures 3.9 calorie kilograms. Also, aspartame is 200 times as sweet as table sugar, so it is eaten in much smaller portions. So your answer would be aspartame.

calculate the atomic mass of lead, if the mass of 0.2 mol of it equals 41.4 grams
The atomic mass of lead : 207 g/mol
Further explanationThe mass of this basic particle is expressed in atomic mass units
This atomic unit uses the standard atomic mass, that is, the C-12 isotope
1 atom C-12 = 12 atomic mass units
The atomic mass of an element (amu = u = g/mol) = the mass in grams of one mole of an element.
The mass of 0.2 mol of Lead equals 41.4 grams, so the atomic mass :
[tex]\tt \dfrac{41.4}{0.2}=207~g/mol[/tex]

Which statement is true about a rock layer deposited on top of another rock layer?
A- It is younger than the rock layer below.
B- It is older than the rock layer below.
C- It is the same age as the rock layer below.
D- It is no different than the rock layer below
Hello there!
Your answer is C.
Answer:
The right option is; A. It is younger than the rock layer below.
Explanation:
A rock layer deposited on top of another rock layer is younger than the rock layer below. This is based on the law of superposition which states that in any undeformed sequence of rocks that are laid down in layers, the youngest layer of rock will be on top of the sequence, while the oldest layer will be at the bottom of the sequence.

How do isotopes affect the average atomic mass of an element?
Answer:
The versions of an element with different neutrons have different masses and are called isotopes. The average atomic mass for an element is calculated by summing the masses of the element's isotopes, each multiplied by its natural abundance on Earth.

Explain in your own words what the law of conservation of mass means
Answer:
Mass can neither be created nor destroyed in a chemical equation, it transfer from one to another form.
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
The solubility of gas in water at 25 C and 1.0 atm pressure of oxygen is 0.061 g/ L. What would the pressure be if the solubility of oxygen water at 25 C is 0.075 g/L
Answer:
P2 = 1.2265 atm (Approx)
Explanation:
Given:
Water temperature = 25 degree Celsius
Pressure = 1 atm
So,
P1/P2 = C1/C2
1 / P2 = 0.061 / 0.075
P2 = 1.2265 atm (Approx)
Changes in which two characteristics can indicate a physical change?
A. Shape
B. Reactivity
O C. State
D. Flammability
Changes in shape and state are the two characteristics which indicate a physical change.
What are physical changes?Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Thermal energy is a form of... A. kinetic energy. B. electrical energy. C. potential energy. D. chemical energy.
Answer:
A. Kinetic Energy
Explanation:
Thermal energy is when the molecules and atoms are vibrating faster due to higher temperatures.
Kinetic energy fits this because the meaning of it is the energy of a moving object.
Since thermal energy comes from moving molecules and atoms, it is therefore a for of kinetic energy.

In covalent bonding, electrons are shared within molecules. This is because..
A.) sharing allows them to achieve a noble gas configuration (octet).
B.) it allows them to become ions.
C.) it allows them to become more polar.
Answer:
You're answer is B.
Explanation:
Covalent Bonds share a negative and positive ion.
In covalent bonding, electrons are shared because sharing allows them to achieve a noble gas configuration. Therefore, option (A) is correct.
What is a covalent bond?A covalent bond is created by the equal sharing of electrons from both bonded atoms. The pair of electrons contributing to this type of bonding is known as shared pair.
Covalent bonds are also known as molecular bonds. Sharing of bonding pairs will make sure that the atoms attain stability in their outer shell as the atoms of noble gases.
Elements with very high ionization energies are not capable of transferring electrons and elements with very low electron affinity cannot accept electrons. Such atoms tend to share their electrons with the other atoms of the same element in a way that both atoms can achieve octet configuration in their valence shell.
This type of association through sharing of electrons between different or the same kinds is called Covalent Bond. Covalent bonds rarely dissociate spontaneously after formation.

Arrange the events in the life of a star in the correct order.
Answer:
1. The temperature increases in the center of a nebula, and nuclei begin to fuse.
2. As the nuclear fusion sets off a chain reaction, the nebula gets hotter and brighter and turns into a star.
3. The star stays in the main sequence stage for a long time.
4. The star runs out of hydrogen and turns into a planetary nebula or a supernova, depending on its mass.
5. Heavy elements are created when the supernova explodes.
